How much coloration can a port add?

Are we talking resonances?

Also couldnt we take precautions in lining the cabinet to avoid any more colorations from reflections and port noises?

I am sorry if this is mentioned before but how much volume does the 15" need for its port tuning?

I dont remember the port tuning but I domt ever remember seeing a chamber volume either. Its...

Well I could just order from Reconing but wanted to see if I could save some money on shipping and give some business to the local guy. I usually buy from the USA for almost everything. Even with...

Amazing build and great pictures. I was looking at building a vintage cabinet and 4345 was the one I am most likely going to do. So this build is VERY helpful to me. :applaud::bouncy:

Ah ok thanks. If you did not want to reveal specifics that would have been fine also. I was just curious where the port was going from the picture. At first I thought i was looking at a dual opposed...

Curious what you ended up doing?

So 8cuft per plans?

I only ask because looking at your picture above it looks like a large port but not sure what length you went in the end.

Hello. I dont believe you stated this but what size cabinet did you go with? 8cuft 25hz or 12cuft 20hz?

I am guessing 12cuft 20hz. Just curious as I am very slowly gathering parts for a possible...

Hey I remember that setup. :)
